Biometrics is an emerging technology used by businesses around the world. There are many advantages associated with biometrics, including providing authentication and access control. Biometrics may be used for access control within large companies, where employees must be authorized before gaining access to company property or sensitive information. They can also be used as part of a security system at the facility or for random access outside of the facility. Many people identify themselves at a job interview based on their face recognition technology, which is often compared to fingerprint scanning.
A variety of biometrics are available for use in identifying individuals. Fingerprints are considered to be a classic form of biometrics, as they are unique to every person. Fingerprints are often collected from all people who have a relationship with the individual such as a parent, spouse, relative, or friend. However, fingerprints cannot be copied or reproduced, which limits their use for identification. Another option for obtaining a fingerprint is to scan the individual’s hand or face using a digital scanning device.
In addition to finger and hand scans, other forms of biometrics commonly used in security systems include iris scans, palm scans, and facial recognition technologies. Iris scans are generally used to verify the identity of individuals while they enter secured areas. Palm scans and facial recognition work to determine whether an individual is who they claim to be. All of these biometrics can provide strong authentication for individuals, which limits the opportunity for identity theft.
Using fingerprints and iris recognition to gain access to secured areas is often impractical, as it requires multiple fingerprints to gain access. Additionally, it is often difficult to remember passwords or access codes. This factor makes it difficult for criminals or unauthorized personnel to access secured areas. It may be easier and more convenient for these unauthorized parties to access a password or access code on a piece of jewelry or other personal item that is attached to an individual, rather than trying to guess a fingerprint or iris recognition.
Biometrics, as previously mentioned, are specific traits of an individual. However, they can also be comprised of combinations of traits and behaviors. As an example, there are several behavioral biometrics commonly used by law enforcement agencies to identify criminal suspects. These traits may include; age, gender, race, language, height, weight, and location. These traits are often used together to formulate a more complete profile of an individual.
Another way that behavioral biometrics can be utilized is for access control. Access control includes elements of physical and electronic surveillance at strategic points around the establishment. When access control is used effectively, it helps prevent unauthorized access by controlling access to physical spaces. This type of access control is often used in large offices or in places of business that have many employees. The physical location and its environment is used as a basis when developing algorithms for identifying individuals.
The modern version of biometrics, known as two-factor authentication, uses two independent factors for authentication. The first factor, usually a fingerprint, is generally chosen by an individual. Two factors are then combined using techniques such as fingerprint scanning or iris recognition technology, resulting in a more secure form of identification.
There are a number of advantages to using biometrics. These advantages include: faster identification and authentication, greater levels of security, and faster and easier authentication. In the future, improved technologies may allow for even more efficient and effective biometrics use traits. For now, however, it has proven to be one of the most secure forms of identification.
